How to check what is the preset CPU frequency of CM4 core in the PSoC6 BLE 062 pioneer board with a Hello World example using ModusToolbox 2.2? I want to increase the CPU frequency at maximum (144 MHz). What are the steps?

Hi,

In ModusToolbox, go to quick panel, open Device Configurator. Inside that open  "Systems" tab.  In the diagram you can see that clk_fast is sourcing the CM4 core. You have to change that to 144MHz. By default FLL might be sourcing the clock. FLL has a range from 24Mhz to 100Mhz. Change the source to PLL which can support till 144MHz. Route the clock to clk_fast(changing clk path for Clk HF0). Additionally you may have to adjust the divider for clk_peri to make within the 100Mhz.
